问题
I tried using Google's feed to JSON converter like this: http://ajax.googleapis.com/ajax/services/feed/load?v=1.0&q=http%3A%2F%2Fnews.google.com%2Fnews%3Foutput%3Drss%26num%3D8
The only problem is that only a maximum of 4 results can be returned. If I go directly to http://news.google.com/news?output=rss&num=8, then there are 8 results. But if I convert it to JSON, there's only 4.
Is there another method of getting Google News results in the JSON format?
回答1:
&num=8 should be part of the load request, not url encoded.
Like this...
http://ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=8&q=http%3A%2F%2Fnews.google.com%2Fnews%3Foutput%3Drss
回答2:
you can use rsz parameter
rsz=4
This argument supplies an integer from 1–8 indicating the number of results to return per page. e.g.
$url="https://ajax.googleapis.com/ajax/services/search/news?v=1.0&rsz=8&q=Tarun%20Gupta";
